Hardware configuration

Introduction
The S7-1500 automation system/ET 200MP distributed I/O system consists of a single-row
configuration in which all modules are installed on one mounting rail. The modules are
connected by means of U connectors, and thus form a self-assembling backplane bus.
You can configure the S7-1500 automation system/ET 200MP distributed I/O system with fail-
safe and non-fail-safe modules.
5.1.1

Hardware configuration of the S7-1500 automation system

Maximum configuration
• The integrated system power supply of the CPU supplies 10 W or 12 W (depending on CPU
type) to the backplane bus. The power budget calculation determines the exact number of
modules (without optional PS) that can be operated with the CPU. The operating principle
is described in section Power balance calculation (Page 121).
• A maximum of three system power supplies (PS) is possible. one system power supply (PS)
can be inserted to the left of the CPU and two system power supplies (PS) can be inserted
to the right of the CPU.
• If you use a system power supply (PS) left next to the CPU, a maximum configuration of
32 modules is possible. The modules occupy slots 0 to 31. If further system power
supplies (PS) are required to the right of the CPU, they also occupy a slot.
